Emergencies and collisions: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

If your brakes fail

  • Pump the brake pedal to temporarily restore hydraulic pressure.
  • If that fails: apply the parking brake gently but firmly while holding the release button.
  • New drivers should practise a parking-brake stop with a qualified instructor.
  • Total brake failure is very rare on modern vehicles; after stopping, don't drive away — call for help.

If your gas pedal sticks

  • First slip your foot under the pedal to lift it; don't reach down with your hands while moving.
  • Then: hazard lights on, shift to neutral, stop as soon as safely possible (preferably off road), ignition off, don't drive away, call for help.

If your headlights go out

  • Check the switch at once; if still out, hazards on, stop safely off the road, call for help.
  • Driving at night without lights is dangerous and illegal.

If you have trouble on a freeway

  • Pull over at the first sign of trouble; don't wait to stall.
  • Mirrors, hazard lights, foot off gas, move to nearest shoulder quickly; never stop in driving lanes.
  • Exit through the door away from traffic if possible; do not raise the hood.
  • Wait inside with doors locked; ask helpers to call police or auto club; use your own phone if you have one.
  • QEW, 400-series and many high-speed roads are patrolled by the OPP; stay with the vehicle.

If your wheels go off the pavement

  • Don't panic; grip wheel firmly; foot off gas; avoid heavy braking.
  • Steer back toward the pavement once under control; be ready to correct steering and increase speed once fully back on.

If a tire blows out

  • Expect strong steering/wheel vibration; foot off gas; steer firmly where you want to go; stop off the road.

In a collision where someone is injured

  • St. John Ambulance recommends carrying a first-aid kit and knowing how to use it.
  • Every driver involved must stay at or return immediately to the scene and give all possible help.
  • Not involved: stop and offer help if police/officials haven't arrived.
  • Must report to police when anyone is injured or vehicle/property damage exceeds $5,000.
  • Engines off, flashers on; warning signals/flares or someone warning traffic.
  • No smoking, matches or flares near vehicles (fuel leak). Vehicle on fire: get people out and well away.
  • No fire/explosion danger: leave injured people where they are until trained help arrives.
  • Trained in first aid: treat by urgency within training (airway, rescue breathing, pressure on bleeding with clean cloth).
  • Not trained: cover a person in shock with a jacket or blanket.
  • Stay with injured people until help arrives.

In a collision where no one is injured

  • Drivable vehicles: move as far off the road as possible ("Steer it, Clear it"); this doesn't affect the police investigation; especially on busy/high-speed roads.
  • Can't move: set warning signals/flares far enough back for traffic to slow or stop.
  • Call provincial or local police depending on location; report if injuries or damage over $5,000.
  • Give police and owners of damaged vehicles: your name and address, registered owner's name and address, plate and permit number, liability insurance card.
  • Get names, addresses, phone numbers of all witnesses.
  • Damage under $5,000: still must exchange information; no police report required.
  • Take photos if safe.
  • If towed: get tow operator's name and licence number/company and know where the vehicle is going.
  • Contact your insurer as soon as possible if you plan to claim.
